a/ZZ tail/m, it 7 my cmtcer'n:

Be it known that i, l /lAX E.-l?nsrnn, a citizen of the United States, a resident F l **t* l- Il i ()1. Leo sow e, .l. eseeu COhll y, scu ,s ant,

State of New York, have invented it new and.

useful improvement in Submarine Structures, such as submarine boa-ts, caissons, and the like, of which the following is e specifics,- tion, reference being bad to the etc/company ing drawing, which illustrates s View, partly in section, of sul'irnerine bout embodying the invention,

i o zittenipt has been miide to show in the drawing the correct construction of c submarine boot, because the invention is, as stated above, equally well sdspted to use in connection with soy submerged structure inclosing a specs in which human beings may be imprisoned, deprived of sir, end sornetimes of food and water us well; but since the iuvei'ition is well sdaipted to use in connection with submarine hosts the general outlines ol such :1 structure have been used drewing to illustrate one application 11). o of he invention. i

epresents the hull of the vessel, caisson, or snnilsr structure. 4

B B two Watertight casings set in the upper pnrhdeck, or shell I of the structure. lhey ch by suitable heavily-hinged lids D D. inc casings are provided with shoulders E, upon which are Water-tight guskets or p: F. The hinges G of the lids ere mode ug andhecvy, and opposite them are bolts ll, which are undercut or beveled at thei rent ends, as shown, end. are su'oported l and adopted to slide through h v metallic loopslike devices I, which are '1 iv bolted or otherwise secured to the U The remends of the bolts are provided with strong upwnrdly-projecting lu s J. The construction of the lids and l" s and the thickness'oi the gaskets are i that when the lids are forcibly pressed coon the gaskets will but under Waterot compression, and so held by the bolts i when their forward beveled ends ere forced the edge oi the lids. I K It ere two tubes threaded at their upper ends end there supported by the bottoms of the casings and near their lower ends by a his training, (indicated at L.) EftGh :1 is 'iurnishciil with o Water-tight gate M, opened end closed by a rack and 1 ion N U, actuated by e rod P, and hand wheel Q, the latter being located beneath the l lid, one in each of the air above.

are each provided. with o wuter-tight packing or stuffing box Q, set in the bottom of the casings, respectively. A ratchet-wheel R is lost on each of the rods P end is provided with a pawl S, which being engaged with the .detents of the ratchet will prevent theturning of the rods P, thus securely holding the gates Mclosed and open as the case may be.

These rods The operation is as follows: If the submerine vessel when submerged should for any reason be unable to come to the surface, or if because of accident or the failure of the usual apparatus to Work, or for any other reason the men in e caisson or similar structure should become imprisoned therein Without supply of air, food, or Water, then the men could be relieved and their lives saved as fol. lows: A. submarine diver, taking with him the ends of two suitable pieces of pipe or hose provided with suitable couplings and a hamm'er, descends upon the structure and with the hammer knocks beck the bolts H H by striking against the studs J J. This releases the lids D D, which are then lifted. Thereupon the two pieces of pipe or hose are coupled to the exposed upper ends of the tubes ll. K, and then the powls S being disengaged from the rutchetevheels R the hendovheels J Q are operated in such manner as to open the gates M M, thus steblishing an inlet and an outlet connection between the interior of the structure, Whatever it may be, and the open Thereupon fresh air, food, and Water, the two latter being preferoblyinclosed in suitable peckeges or receptacles, may be supplied through the tubes and free fresh air circulation established through them.

The stated tubular connections may be c toblished and broken-es often as desired or maintained untilplens can be put into execution for the release of the imprisoned men.

it will be obvious to those who are familiar with this subject that many alterations may be made in the mechsnicel details of the opperotus and yet all essential features oi the invention be employed. 1 therefore do not limit myself to the details as shown.

I cloin1 1. In a structure of the class stated, recesses made in the outer surface thereof, Water-tight lids adapted to close the outer side of the recesses, a pair of tubes extending from the interior of the structure to and into the recesses, means whereby pipes or hose may be connected with the outer ends of the tubes Within the recesses, gates constructed and arranged to open and to close the tubes and means located witinn' the recesses ior actuating the gates.

2. In a structure of the class stated, re- 5 cesses made in the outer surface thereof, Water-tight lids adapted to close the outer side of the recesses, a pair of tubes extending from the interior of the structure to and into i the recesses, means whereby pipes or hose may be connected with the outer ends of the tubes Within the recesses, gates constructed and arranged to open and close the tubes, means located within the recesses for actur ating theegates and means to lock the gates in their open and closed positions.

In testimony whereof i have signed my name to this specification in the presence oi two subscribing itnesses.
